Summary
🤩
RockstarQi Zhang is a software engineer and applied economist with seven years of experience building production-scale auction and experimentation systems for ad platforms at ByteDance. At ByteDance he invented a novel ads auction mechanism and payment formula that materially outperformed oCPM and now accounts for a substantial share of revenue, while preserving key auction-theory properties like incentive compatibility and anti-fraud safeguards. He also designed an efficient long-term experiment framework generalized from cookie-cookie-day and an economic auditing tool that surfaced subtle disturbance effects and boosted revenue. A former founder with a mathematical and statistical background from Peking University and UC Berkeley, Qi blends rigorous theory with pragmatic engineering to deliver auditable, revenue-driving systems. Notably, his work focuses on measurable long-term impact rather than short-term lift, reflecting a rare combination of product-minded economics and hands-on software development.
